HOOK.

To all whom it may concern:

Be it known that I, MARTIN T. OLsTAD, a citizen of the United States,residing at Greenport, in the county of Suffolk and State of New York,have invented new and useful Improvements in Hooks, of which thefollowing is a specification.

This invention relates to books and more especially to detachable hookswhere it may be necessary to disconnect ropes or cables with littledelay and it consists of a hook having a perforation at one end and aremovable section at one side in order to release the rope from the hookitself as will be more fully described in the following specification,set forth in the claim and illustrated in the drawings, wherein,-

Figure 1 is a side elevation partly in section, showing the hook closed.F ig. 2 is a side view showing the hook open.

The rigid section 5 of the hook is of ordinary construction and has anopening 6 at its lower end through which an eye 7 may be inserted and arope secured about the eye.

One side 8 of the hook is removable so that a rope may be passed intothe open space 9 when desired. This side 8 also has a perforation 10 tocarry the ring 7 and its rope and the side 8 is provided with a passagein which is located a locking bolt 11 whose stem 12 is surrounded by aspring 13 and carries at its lower end a thumb piece 14;. The bolt 11projects into a recess 15 of the over-hanging section of the hook and aprojection 16 of the side 8 is perforated to fit over the nose 17 at theend of the hook and which is adapted to strengthen the sideSpecification of Letters Patent.

8 and relieve the bolt 11 from the entire strain.

Then the rope is to be inserted in the opening 9, the bolt 11 isretracted by means of the thumb piece 14 so that the side 8 may be swungoutward as shown in Fig. 2 and the rope inserted. The movable side isthen replaced and the nose 17 prevents swinging movement, while the eye7 prevents the lateral movement of the movable side.

This construction provides a hook of considerable strength and few partswhich are liable to become injured and get out of order.

It is obvious that the parts may be otherwise arranged or modifiedwithin the scope of the claim without departing from the essentialfeatures above described.

hat I claim as new and desire to secure by Letters Patent is,-

A hook comprising a member having a bill provided at its end with arecess, said member having at the side of the bill an outstanding noseone edge of which is in alinement with one edge portion of the recess, aside member having a perforation adapted to receive the said nose, and aspring pressed bolt mounted upon the side member and having an endportion normally disposed partially across the said perforation.

In testimony whereof I afiix my signature in presence of two witnesses.
